Can I make a scrolling text panel draggable?

Hello everyone - my first post in this nice place.

I’m trying to make a scrollable dynamic text field in a movie clip which can be dragged to different positions in the main movie. I’ve found some great tutorials showing how to build a masked panel that scrolls with mouse position, but when I nest this in a draggable movie clip the scroller stops working. I can sort of do what I want by linking the _x and _y of the text field to that of the draggable background using onMouseMove (and having both on the main timeline) but this is clumsy and the text lags behind the background when it’s dragged. Is there a way to do it with the text nested inside the background? I’m hoping to avoid components to keep file size down. And I’m kind of a newbie.

Thanks in advance for any ideas.
